Answer 1

Hint: The students should recall what voice is, and then read the sentence carefully to determine in which voice it is given. Then the option which correctly changes the voice of the sentence should be chosen.

Complete answer:
We know that passive voice is the voice used to indicate that the grammatical subject of the verb is the recipient (not the source) of the action denoted by the verb.
In the given question, we have to find out which of the options includes a sentence where the tense is the same as that in the sentence in question (past perfect tense) and is grammatically correct.
Let us thus analyze the options given to us in this question -
Option (a.), 'The smugglers are arrested by the police', refers to ‘simple present tense’.
Therefore, option (a.) is incorrect as the answer should include a sentence where the tense is the same as that in the sentence in question (past perfect tense).
Option (b.), ‘The smugglers has arrested by the police', refers to ‘has’ and ‘arrested’ simultaneously. Therefore, option (b.) is incorrect as ‘smugglers’ is plural whereas ‘has’ is used for singular nouns, thus is grammatically incorrect.
Option (c.), ‘The smugglers have been arrested by the police', refers to ‘past perfect tense’.
Therefore, option (c.) is correct as we needed the answer to include a sentence where the tense is the same as that in the sentence in question (past perfect tense).
Option (d.), ‘The smugglers are being arrested by the police', refers to ‘present continuous tense’. Therefore, option (d.) is incorrect as the answer should include a sentence where the tense is the same as that in the sentence in question (past perfect tense).

Note:
In this question, it will be helpful for the student to recall the concept of active voice. Active voice is the voice used to indicate that the grammatical subject of the verb is performing the action or causing the happening denoted by the verb.
